The mountain area of southern Anhui Province is the region where the mountains are high and the slops are steep,and it is an area where collapse,landslide and debris happened frequently,besides,it suffers the geological hazards most seriously in Anhui Province.The results of our study show that the fragile geological environment is the basis of the geological hazards while heavy rain is the main induction factor of collapses and landslides,and human engineering activities are the main factors which aggravate the geological hazards.In June and July,the geological hazards occurred collectively,especially in the places where sand rock,shale rock,phyllite distributed.Carrying out a detailed investigation of geological disaster,improving the precision of geological hazard meteorological forecasting and slowing down the human engineering destruction strength,as well as,improving the mass monitoring and preventing system will be the effective measures to prevent geological hazards in this area.
